IMPROVEMENT IN LAMP-EXTING-ISHERS.

The Schedule referred to in theseLetters Patent and-:1` `king part of the same.

To all whom 'it lmel/y concern:

VBe it known that I, CHARLES LANZENDORFER, of

Chicago, in the county of Cook, and State of Illinois,

h ve invented certain new and useful Improvements in Safety-Attachment for Lamps and I do hereby declare that the following is a full, clear, andl exact description thereof, reference being had to the accompanying drawings, making part of this speciiication, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

This invention consists in a novel arrangement of devices to be attached to lamps, Vand which, when the lamp is overturned, shall automatically turn down the wick, and thus extinguish the iiame of the lamp, and prevent all danger from iire or explosions caused by the ignition of the oil when the lamp is broken.

In the drawing- Figure 1 is a side elevation of the burner of an ordinary coal-oil lamp with my improvement applied.

Figure 2, anelevation of the opposite side.

The apparatus consists of cog-wheels, operated by a coiled spring, and connected with the spur-wheel lwhich operates the wick, in such a manner that when the spring is wound up, and then allowed to run down, it will cause the gear-wheels to revolve and carry the wick down, and extinguish the light, the wheels being held by a pawl and ratchet-wheel, the pawl hav ing connected to it, by a cord, a weight, which, while the lamp stands upright, rests in a cup provided for that purpose, and allows the pawl to engage with the teeth on the ratchet-wheel, but when the lamp is inclined at forty-tive degrees or more, this weight falls out from the cup, and, through the medium of the cord, raises the pawl, and thus allows the spring to operate the mechanism and extinguish the iianic.

As seen in Ithe drawings, A represents the head or burner ofan ordinary coal-oil7 lamp, a being the wicktube, and 0, the shaft to which the spur-wheel is secured that operates the wick.

To one end of this shaft o, outside of the body A, I attach a cog-wheel, B, and at one side of the body A, a case or barrel, D, held in position by an arm, b, which passes through a lug, c, fastened to one side of the body A, the arm being clamped in place by the thumbscrew d.

Within the case I),.I place a coiled spring, F, as shown in iig. 2, one end of said slfri'ng being secured to the inside ofthe case, and the other end to a shaft,

n, running through the centre of the case, this shaft.

projecting out through the case at each end, and having attached to it, at one end, outside of the case, a cog-wheel, C, meshing into the wheel B, and at the opposite end the ratchet-wheel G, also outside of the case.

To the outside of the case D, above the ratchetwheel G, I pivot the pawl F, which engages with the teeth on wheel G,and prevents the spring from unwinding.

Connected-to the loose end of this pawl, by a cord,

g, is a weight, H, for the sake of convenience, made in the form of a ball, which, when the spring is wound up, and the lamp in an upright position, rests in a cup, I, said cup being supported by the stem e, which passes through a stud on one side of the case I), and is clamped by the thumb-screw f.

The apparatus being thus constructed, operates as.

follows:

The weight H is placed in the cup I, and the wick brought to the desired height by turning the-wheel B, which at the same time operates the wheel C and winds up the spring E, which is prevented from unwiuding by the pawl F engaging with wheel G, the-cord g being of sufficient length to allow the pawl to fallin place when the weight is in the cup.

So soon, however, as the lamp is inclined suciently to causel the weight to roll from the cup, it will, through the medium of the cord, (which passes ,up4 through` a small opening in the bottom of the cup,) raise the pawl, when the spring will cause"the wheel C to revolve, and it, in turn, operate wheel B, and thus carr the wick down, and extinguish the light.

When the lamp is to be relighted, it is,only necessary to turn" the wheel B until the wick is brought to the proper height.

T o limit the revolutions of the wheels when the pawl is raised, and prevent the wick from being carried so far down that the spur-wheel ceases to have hold upon it, I provide the wheel C with a circular slot, L, and secureto the drum 'a stop or projection, fi, extending out into the slot, thus limiting the movement of the wheels to a certain extent, but yet allowing suiicient 'play-to bring the wick far enough down to extinguish `the light.

The wick, as it burns off, will iinally become so short that when the wheel is turned as far as the slot will permit, it 'will not be brought high enough to burn.

To provide for adjusting it, and thus remcdying this difficulty, the screw d may be loosened, which will release the arm I1, when the barrel may be moved sidewise far enough to disconnect the wheels B and C, when the wick may be adjusted, as required, after which the barrel or case may be shoved back in place and secured. r

It is obvious that this device may be applied to any size or style of lamp, and it is a simple, cheap, and eiiicient device for the purpose intended.

Haviu g thus fully described my invention,

What I claim, is-

l. The method of automatically extinguishing an overturned lighted lamp, by the mechanism, consisting of the wheels B C Gr, spring E, and pawl F, when constructed'and arranged substantially as hrein described, to bc operated by a weight, H, as herein set forth.

2. rlhe weight H and cord g, in combinationwith the mechanism herein described, when constructed and arranged to operate as set forth;
